Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural working machines face complex assembly and conversion processes for crossbeams, requiring manual handling and use of tools for connecting and guiding auxiliary tools.
Innovation Solution
The implementation of connecting means on the receptacle and bridging element that allow for tool-free, form-fitting connection of the bridging element to the receptacle, simplifying assembly and disassembly of the crossbeam and associated bearing device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional connecting means are used for assembling the crossbeam, then the connection is operationally reliable, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The connecting means is divided into two complementary parts: a first connecting part integrated into the receptacle and a second connecting part integrated into the bridging element. This segmentation allows each part to be simple in design while their combination provides secure, tool-free connection, resolving the contradiction between simplicity and reliability.
Solution Approach 2:
The connecting means is designed to be self-aligning and self-securing through form-fitting engagement. The complementary shapes of the connecting parts automatically guide each other into the correct position during assembly, eliminating the need for tools or complex alignment procedures while ensuring reliable connection.
2Reliability
If traditional fastening methods are used for the crossbeam, then the connection is secure, but the assembly and disassembly process requires tools and manual handling
Solution Approach 1:
The form-fitting connecting parts are designed to engage automatically without tools. The geometric complementarity of the connecting features provides self-guidance and self-locking, allowing operators to assemble and disassemble the crossbeam quickly by simple insertion and removal motions, eliminating the need for screwdrivers, wrenches, or other manual fastening tools.
Solution Approach 2:
The invention replaces traditional mechanical fastening systems (screws, bolts, clips requiring tools) with a direct form-fitting engagement system. The connecting parts rely on geometric interlocking and elastic deformation of the bridging element rather than threaded engagement or clamping mechanisms, dramatically simplifying the operation while maintaining security.
3Ease of operation
If the bridging element is designed as a single piece, then the assembly process is simplified, but the manufacturing complexity increases
Solution Approach 1:
The invention replaces traditional multi-part mechanical assemblies (multiple bolts, clips, or separate components) with a single integrated bridging element. This monolithic design simplifies assembly to a single insertion motion while the connecting features are formed directly into the piece through manufacturing processes, trading some manufacturing complexity for significant operational simplicity.
